Problem with JRadioButtons....

Question

hi,
we were dealing with a grup of buttons added on a JFrame,
the problem is,when i choose any of the buttons and click the Submit button,the action is supposed to open a file and write the numeber of times its pressed.i wass using hthe ItemListener() for the RadioButtons and ActionListener for the Submit button,and here is the code.....
private JRadioButton bg[]=new JRadioButton[bgOptions];
private String bglabels[]={"A","B","c","d"};
private JButton Submit=new JButton("SUBMIT");
private JPanel lpanel=new JPanel();
lpanel.add(Submit);
Submit.addActionListener(this);
public void initBGgroup()
bgpanel.setBackground(Color.white);
bgpanel.setLayout(new BoxLayout(bgpanel,BoxLayout.Y_AXIS));
          for (int k = 0;k < 5;k++)
     bg[k]=new JRadioButton(bglabels[k]);
bg[k].addItemListener(this);
          bgpanel.add(bg[k]);
          optGroup2.add(bg[k]);
          bgpanel.setBorder(BorderFactory.createTitledBorder("ButtonGroup"));
public void itemStateChanged(ItemEvent e)
if(e.getStateChange()==ItemEvent.SELECTED)
JRadioButton b = (JRadioButton)e.getSource();
try{
String ss=b.getText();
System.out.println(ss);
if (ss=="A")
DataOutputStream aps=new DataOutputStream(new FileOutputStream("ap"));
DataInputStream aps1=new DataInputStream(new FileInputStream("ap"));
Integer ap12=new Integer(aps1.readInt());
System.out.println(ap12);
     int ap1=ap12.intValue();
int apto=ap1+1;
System.out.println(apto);
aps.writeInt(apto);
aps.close();
     aps1.close();
else if (ss=="B")
DataOutputStream ans=new DataOutputStream(new FileOutputStream("an"));
DataInputStream ans1=new DataInputStream(new FileInputStream("an"));
Integer an12=new Integer(ans1.readInt());
     int an1=an12.intValue();
int anto=an1+1;
ans.writeInt(anto);
ans.close();
     ans1.close();
else if (ss=="C")
          DataOutputStream bps=new DataOutputStream(new FileOutputStream("bp"));
          DataInputStream bps1=new DataInputStream(new FileInputStream("bp"));
Integer bp12=new Integer(bps1.readInt());
int bp1=bp12.intValue();
int bpto=bp1+1;
bps.writeInt(bpto);
bps.close();
     bps1.close();
else if (ss=="D")
     DataOutputStream bns=new DataOutputStream(new FileOutputStream("bn"));
DataInputStream bns1=new DataInputStream(new FileInputStream("bn"));
Integer bn12=new Integer(bns1.readInt());
int bn1=bn12.intValue();
int bnto=bn1+1;
bns.writeInt(bnto);
bns.close();
     bns1.close();
catch(Exception e1)
e1.printStackTrace();
public void actionPerformed(ActionEvent e)
Object obj=e.getSource();
if (obj==Submit)
//apf,anf,bpf,bnf are the textfileds in which the totals r displayed
read1("ap",apf);
read1("an",anf);
read1("bp",bpf);
read1("bn",bnf);
public void read1(String st2,JTextField st3)
try{
DataInputStream tfdis = new DataInputStream(new FileInputStream(st2));
int atot=tfdis.readInt();
Integer alltot = new Integer(atot);
String display = alltot.toString();
st3.setText(display);
is thsi the way to handle,i was getting problem with butoon when i click them...please advice...

Thanks for the Sugestion..but the problem is with the ItemListener
it is giving errors at runtime,without going to the submit button
when i select a button...don't know why?i even changed the ss=="a" to (ss.equals(a))but no luck....
